Chosen Solution
Hi. I just bought a broken iPhone 6, its arriving soon and I’d like to know your thoughts as to what I should try first. The guy who owned it said it has a broken LCD after it fell on the floor, it hit the left chassis as seen in the photo and the glass near the front camera is chipped. The LCD was then showing some white stripes, and he tried to update the iOS to “solve” the problem and now its on a reboot loop. Supposedly, the update was successful but it fails to start for the first configuration. It was also supposed to be working fine before it was dropped. He has replaced the battery but it is still stuck in a boot loop but he has not replaced the screen. The phone has not come in contact with water. I also asked if he has tried using DFU mode and he said he hasn’t tried. Where do you think I should start? https://ibb.co/eGFuRw https://ibb.co/fGMvYb https://ibb.co/eQjAzG
It probably loosened some pins connecting the screen to motherboard. I wouldn’t be surprised if the screen (and maybe motherboard too) wasn’t damaged. I would recommend opening it up and checking it out. There are guides for this, or you can go to a pro.
I agree with Edison about the motherboard issue. I have seen youtube videos of pros who fix board level issues on iPhones and they get phones that have chips on the boards damaged from simple drops. I would consult a board level repair pro.
